What did rutherfords gold foil experiment help him conclude

It allowed him to realize that the mass of an atom is concentrated at its center because the atoms mostly went through the foil but some were deflected. He also realized that an atom probably wasn't just empty space and scattered electron and it had a positive center.

Answer: the existence of the nucleus of an atom

Explanation:

Rutherford's Gold Foil Experiment proved the existence of a small massive center to atoms, which would later be known as the nucleus of an atom. Ernest Rutherford, Hans Geiger, and Ernest Marsden carried out their Gold Foil Experiment to observe the effect of alpha particles on the matter.

Most of the space inside the atom is empty because most of the α-particles passed through the gold foil without getting deflected. Very few particles were deflected from their path, indicating that the positive charge of the atom occupies very little space.

If 3 moles of a compound use 24 J of energy in a reaction, what is the A<br> Hreaction in J/mol?
erma4kov [3.2K]

Answer:

+8 J/mol

Explanation:

The following were obtained from the question:

Mole of the compound = 3 moles

Heat Energy used = 24J

Hreaction =?

The heat of reaction is the energy released or absorb during a chemical reaction. It is can obtained mathematically by the following equation:

Hreaction = Heat energy/mole

With the above equation, we can easily find the Hreaction for the question given as follow:

Hreaction = Heat energy/mole

Hreaction = 24J / 3mol

Hreaction = 8 J/mol

Since the compound used the energy, the Hreaction is +8 J/mol

An ant carries a morsel of food 4.26 meters along a straight path to his nest. he then turns around and follows the path back to
SVEN [57.7K]
<span>Answer: 0.00 meters

  Solution:

    Step 1: Define displacement DISPLACEMENT = a vector quantity that describes "linear or angular distance in a given direction between a body or point and a reference position."

  Step 2: Understand the question

 Assumption 1: Assume that when the ant moves 4.25 meters from its origin to its nest, it is moving in a positive direction (on a graph you would draw a line along the x-axis from its origin to +4.25).

  Assumption 2: Assume that when the ant "turns around...back to the source of food", it is moving back in the negative direction (towards the origin).

   Step 3: Analyze the question

  What is the distance between where the ant originally started and where it ended its journey?

  The ant started and ended its journey in the same place.

 While it traveled a distance of 8.52 meters (2 * 4.26 = 8.52), it's displacement is actually 0.00 meters (4.26 + (-4.26) = 0.00)

  Therefore, the answer is 0.00 meters</span>

(01.07 но) An experiment was conducted to determine the density of a liquid. The table shows a partial record of the experiment
Anestetic [448]

Answer:

How do you find the density of a liquid experiment?

To measure the density of a liquid you do the same thing you would for a solid. Mass the fluid, find its volume, and divide mass by volume. To mass the fluid, weigh it in a container, pour it out, weigh the empty container, and subtract the mass of the empty container from the full container.
